Usually the forging process includes the following processes: selecting the high quality steel billets for blanking, heating, forming and forging cooling. In production, the different forging methods are selected according to forging qualities and consumption batch sizes of the forging when you purchase it. The concrete production methods of forged steel flanges are as following:
Free forging has great versatility, therefore it is usually used for forging simple-shaped single piece and small batches of consumption forgings. Free forging equipment has air hammer, steam, air hammer and hydraulic press, etc., it is respectively suitable for small, medium and large forgings processing. The basic process of free forging: The shape of forged steel flanges forgings is forged the blank gradually by some fundamental deformation procedures in the process of forging.
The dimensional accuracy of die forgings are very high and machining allowance is small. The fiber structure distribution of forged steel flanges forgings is more reasonable, therefore it can further improve the service life of parts. The production efficiency of die forging is high and the operation is simple, it is easy to complete mechanization and automation.
Upsetting is the operation process to forge the raw billet along the axial direction to reduce the height and increase the cross section. This type of forged steel flanges process is usually used for forging gear billets and other disc-shaped forgings. Upsetting can be divided into two types: total upsetting and partial forging.
Drawing is a forged steel flanges process to increase the length of the blank and reduce the cross section. It is usually used to forge the workblank of shaft parts, such as lathe spindle and connecting ro, etc.
